The gesture, keyboard command, and Perkins-style keyboard commands for Touch and Sound Curtain do not Work.

Description

The braille display commands for activating Sound Curtain (Space with dots 1-2-3-4-5-6-7) and Touch Curtain (Space with Dots 1-2-3-4-5-6-8) do nothing when activated. Assigning alternative commands or gestures for these functions also does not work.

Steps to reproduce

With a braille display, perform the command to enable Sound Curtain (Space with dots 1-2-3-4-5-6-7) and Touch Curtain (Space with Dots 1-2-3-4-5-6-8).

Workaround

these settings can still manually be enabled by going to Settings > Accessibility > VoiceOver > Braille > Sound Curtain, or Settings > Accessibility > VoiceOver > Braille > Touch curtain respectively.
For Sound Curtain, lower the device volume to 0%.
One can also add the Sound Curtain to VoiceOver's Quick Settings to save a few steps. Head to Settings>Accessibility>VoiceOver>Quick Settings and select "Sound curtain". Since Touch Curtain does not have a Quick Settings option, this workaround does not apply.
